An assist t movement of the wrappers along the opening H, in alignment with the surface of tube It.- the base it, is provided in the wall of the re- Disposed on the top of the bed frame It along 69 ceptacle i2 through which the bottom article of each side of a longitudinal slot 48 are ways 49 60 in which is mounted a reciprocating slide 58. A bolt 5| threaded through the slide 58 and extending through the slot 48 operatively connects the slide to suitable reciprocating means to be described. Secured on the upper surface of the slide 58, by means of bolts 52, is a block 53 having formed on one end thereof a plurality of outwardly extending spaced lugs 54 having secured therebetween a pair of .opposed elongated transfer fingers 55 and 56. 'The ends of transfer fingers 55 and 56 during their reciprocatory movement pass through a tubular Wrapper disposed in the magazine I8 and enter the receptacle I2 through the opening II, grip an article disposed therein and withdraw it from the receptacle and deposit the same within the wrapper in the magazine I8.

Mounted on the bed frame Illin the path of the reciprocating transfer fingers 55 and 56 are longitudinal spaced opposed rollers 51 and 58 which cooperate to close the space between the transfer fingers when the ends of the fingers are at the extreme end of their outward stroke, thereby causing the fingers "to grip the bottom article of the stack disposed in the receptacle I2. The rollers, in operation, are effective tomaintain the ends of the' fingers in gripping relation with the article during the return stroke of the fingers, and to cause them to release the article before the end of the stroke is reached to permit the removal of the wrapped article from the magazine I8 and the positioning of another wrapper in the magazine prior to the succeeding outward stroke of the transfer. fingers. The upper roller 5! is mounted in fixed position in a bracket 59, whereas the lower roller 58'is mounted for vertical movement with respect to the finger 56,

serving to move the latter toward the finger 55.

The roller 58 is journalled in the end of a block 68 slidably mounted in a sleeve 6| extending through an aperture 62 in the bed frame I8. The lower end of thesliding block 68 is provided with a cam follower or roller 63.

The mechanism for operating the plunger 35 disposed in the magazine I8 for successively projecting tubular wrappers past the spring members 32 and 33 is most clearly illustrated in Figures l and 3. This mechanism consists of a member 64, one end of which is pivotally mounted as at 65 in a bracket 66 secured to the bed frame III.

The other end of'the member 64 terminates in a pair of spaced arms 61 and 68. The end of the arm 61 has pivoted thereto a link 69, having its upper end secured to an outwardly extending pin I carried on the upper end of the plunger 35. The end of the arm 68 is slidably receivedin a guide slot II of a bracket I2. Movement of the member 64 is effected through a cam roller I3 carried by the block 53 and engageable with the lower surface of the member 84. The upper surface of a pivoted plate I4 is adapted to'be moved under the lower surface of the arm 68 when the samehas been moved to its uppermost position against the compression of the spring 38 by the roller I3 engaging withthe member 64, and holds it in said elevated position until the plate I4 is moved out of position by means of a cam, to be described, engageable with the lower end thereof. Upon release of the plate "I4 from the arm 68 the plunger 35 is moved downwardly by spring 36 thereby positively moving atubular wrapper,-

which has been fed into the passage 24 while the plunger 35 was held in its uppermost position, past the inner ends of the spring members 32 and 33.

Supported beneath the top of the bed frame tubular wrappers.

ID are a pair of spaced bearings I and I6 havingjournalled therein a cam shaft 'II upon which is keyed a spiral cam element I8. The spiral cam "I8 islpositioned on the shaft 11 below the slot 48 and has formed therein a groove I9 in which rides a cam follower 80 freely mounted on the end of the bolt 5|. Reciprocation of the slide 58 together with the transfer fingers carried thereby is actuated by the cam 18, one revolution thereof effecting a complete reciprocation of the slide 50. The shaft I1 also has cams 8| and 82 secured thereon, cam 8| engaging the lower end of the pivotal plate 14 and serving to pivot the same and thereby move the upper surface thereof into and out of engagement with the lower su'rface of the arm 68, during predetermined portions of a single rotation of the shaft 1]. The cam 82 is so positioned on the shaft I! as to be engaged by the cam follower 63 carried on the lower end of the slidable block 68. The cam 82 is so formed and positioned on the shaft 'I'I that the roller 58 actuated thereby urges the transfer finger 56 toward the finger 55 on the return stroke of the fingers, releasing the finger 56 just prior to the end of the return stroke thereby releasing the article between the ends of the fingers 55 and 56. The release of the article by the fingers is so timed that the article is deposited within a tubular wrapper positioned within the magazine I8. i

Mounted on the shaft 'I'I between the cam 82 and-the bearing I5 is a disk 83, the periphery of which extends through a transverse opening 84a in the bed frame I0 and into the space between the members 28 and 2| of the magazine I8. Ex-

tending outwardly from the periphery of the disk 83 is a finger 84 the outer end of which has formed therein a notch 85. On either side of the finger 84 are provided guide members 85 which engage the outer surface of the lower ends of the members 28 and 2|. The disk 84 is so positioned on the shaft 11 that the finger 84 removes the assembled article and wrapper from the magazine immediately after the transfer fingers have released the article. A revolving brush 81 carried ina bracket 88 secured to the side of the frame I0 serves to dislodge the wrapped article from the notch 85-and direct it into any suitable container.

The shaft IT has keyed thereto a sheave 88 which is engaged by the driving belt 45 to rotate the hopper 42 as above described. Any suitable means (not shown) may be provided for rotating the shaft 11.

The operation of the apparatus described hereinabove may be briefly summarized as follows:

The receptacle I2 and magazine I8 are filled respectively with rolled, thin, rubber articles, and

The cam shaft TI is continuously rotating, and at the beginning of a cycle of operation, the slide 50 and the transfer fingers 55 and 56 carried thereby are at the extreme right, as viewed in Figure 2. Rotation of the cam I8 moves the slide to the left causing the transfer fingers 55 and 56 to traverse the magazine I8 through the openings 28 and 29 and a tubular wrapper aligned therewith, and enter the receptacle I2 through the opening IT, The ends of the fingers 55 and 56 are open as they enter the receptacle I2 and positioned, respectively, above and below the article disposed on the base I 5. As the slide has been moving on its outward stroke the cam roller "I3 carried therebyhas raised the member 64, which through arm 51, link 69 and pin connection I8, raises the plunger 35 in passage 24, so that a tubular wrapper may be introduced into the passage 24 from the feed tube l9. When the plunger 35 has reached its uppermost position cam 8| comes into play to pivot plate 14 and bring the upper surface thereof under the arm 68 thereby holding the plunger in its raised position against the action of spring 36.

At this point, which is the end of the outward stroke of the slide 58, the cam 82 acts through the follower 63, slide block 60, and roller 58 to move the finger 56 towards the finger 55. This movement of the roller 58 causes the ends of the transfer fingers 55 and 56 to grip the edge of the article. The cam 18 then starts the return stroke of the slide 50, during which movement the cam 82 maintains the fingers in gripping relation with the article. The fingers draw the article from the receptacle l2 and into the tubular wrapper disposed in the magazine. Just before the slide has reached the end of its return stroke the cam 82 permits the roller 58 to drop, thereby permitting the fingers to open and release the article. The release of the article by the fingers is so timed that the article is substantially centered within the tubular wrapper. Immediately following the release of the article the disk 83 has moved around to bring the notch of the finger 84 carried thereby into position to remove the wrapped article from the magazine. Upon the removal of the article from the magazine the cam 8| moves the end of the plate it out of engagement with the under surface of arm 68 thereby releasing plunger 35 whichis urged downwardly by spring 36 to project a wrapper past the ends of the spring members 32 and 33. The device is then in position to repeat the foregoing cycle of operation.

Having thus described the invention what I desire to obtain by Letters Patent is defined in the appended claims.
